Connections, Certificates and Authentication

Connections

  1. HTTP store
  2. HTTPS store
  3. NetScaler Gateway 10.5 and later
  4. Web Interface 5.4

Citrix Receiver for Windows can be connected to the VDA or an ICA session can be established on windows domain-joined machines, managed devices (local and remote with or without VPN) and non-domain joined machines.

Certificates

  1. Private (self-signed)
  2. Root
  3. Wildcard
  4. Intermediate

Private (self-signed) certificates

If a private certificate is installed on the remote gateway, the root certificate of the organization’s certificate authority must be installed on the user device to successfully access Citrix resources using Citrix Receiver for Windows.

Note

If the remote gateway’s certificate cannot be verified upon connection (because the root certificate is not included in the local Keystore.), an untrusted certificate warning appears. If a user chooses to continue through the warning, a list of apps is displayed but the apps cannot be launched.

Installing root certificates

For domain-joined computers, you can use Group Policy Object administrative template to distribute and trust CA certificates.

For non-domain joined computers, the organization can create a custom install package to distribute and install the CA certificate. Contact your system administrator for assistance.

Wildcard certificates

Wildcard certificates are used on a server within the same domain.

Citrix Receiver for Windows supports wildcard certificates; however, they must be used in accordance with your organization’s security policy. In practice, an alternative to wildcard certificates is a certificate containing the list of server names with the Subject Alternative Name (SAN) extension is considered. These certificates are issued by both private and public certificate authorities.

Intermediate certificates

If your certificate chain includes an intermediate certificate, the intermediate certificate must be appended to the NetScaler Gateway server certificate. For information, see Configuring Intermediate Certificates.
